                            <p>这个Javascript组件运用了最新的 XMLHttpRequest Level 2 规范，提供了通过包含上传进度条的Ajax进行文件上传追踪的功能。本组件提供了两种上传文件的方式： <code>select</code> 和 <code>drop</code>。 <code>select</code> 请求只能被用在<code>&lt;input type=&quot;file&quot;&gt;</code> 元素中，而 <code>drop</code>基本可以用在任何元素，通过从桌面将文件拖拽到指定元素就能轻松实现上传。记住，本组件并不在服务器上处理文件上传。</p>
                            <p><span class="uk-badge uk-badge-danger">注意</span> 使用此组件需要额外添加 <code>upload.css</code> 文件，在<code>css/components</code>文件夹中。此组件需要额外添加 <code>upload.js</code> 文件，在<code>js/components</code>文件夹中。</p>

                            <p>上传组件需要根据你的要求单独进行实施。在我们的例子中，我们使用<a href="placeholder.html">占位符</a>和<a href="form-file.html">文件表单</a>，同时使用了<code>drop</code> 和 <code>select</code>请求。另外，还是用了<a href="progress.html">进度条</a>来显示上传进度。</p>
